The Gender, Adolescent Transitions and Environment (GATE) Program is housed within the Sociomedical Sciences (SMS) Department at Columbia University Mailman School of Public Health. GATE is an innovative research and practice program dedicated towards improving the lives of adolescents and women around the world through addressing issues related to pubertal health transitions, menstrual hygiene management (MHM), and access to sanitation. This includes contributing to building the evidence and learning on best practices, policies, and cross-sectoral partnerships focused on addressing these critical issues in low resource contexts and humanitarian emergencies globally.
